net: tun: Remove redundant assignment to ret
Variable 'ret' is set to zero but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: drivers/net/tun.c:3008:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores] Reported-by: Abaci Robot <abaci@linux.alibaba.com> Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> Link: https://lore.kernel.org/r/1619603852-114996-1-git-send-email-yang.lee@linux.alibaba.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
